DESCRIPTION
The Simtek STK11C68 is a fast static RAM with a
nonvolatile element incorporated in each static
memory cell. The SRAM can be read and written an
unlimited number of times, while independent non-
volatile data resides in the Nonvolatile Elements.
Data transfers from the SRAM to the Nonvolatile Ele-
ments (the STORE operation), or from Nonvolatile
Elements to SRAM (the RECALL operation), take
place using a software sequence. Transfers from the
Nonvolatile Elements to the SRAM (the RECALL
operation) also take place automatically on restora-
tion of power.
The STK11C68 is pin-compatible with industry-
standard SRAMs. MIL-STD-883 device is also
available (STK11C68-M).
